STORAGE-BATTERY TAR.

To all whom it ma'y concern Be it known that I, CHESTER W. BENTLEY,

a citizen of the United States, residing at 'Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Storage- "Battery Jars, of which the following is a specification.

This inventiori' relates to electrical apparatus, and more particularly to, storage batteries, and "has for its object to provide a battery jar ,of an especially desirable type, in which the liability of local short circuiting is largely obviated.

Another object is to provide. a battery jar having a cover, engaged thereover in such a way as to hermetrically seal the jar.

Another object is to provide a cover for battery jars especially adapted to receive electrodes therein so that they will be perfectly insulated against short circuit.

Another object is to pmvide a jar and cover having special interlockingconstruction adapted to simple manipulation.

'Other objects and advantages will be apparent from the following description, and it will be understood that changes in the specific structure shown and described may be'made within the scope of the claims and that any suitable materials may be used without departing from the spirit of the invention.

In the drawings forming a portion of this specification, which represent but one end portion of the device and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a top plan viewof the receptacle, Fig. 2 is a side view of the receptacle, Fig. 3 is a top view of the receptacle having the cover thereon, Fig. 4 is a cross sectional view of the cover, engaged upon the receptacle, and having plates and electrodes engaged therewith, Fig. 5 is an end view of the upper portion of the receptacle with the top engaged thereon, partly shown in cross section,

Referring to the drawings, there is shown.

formed registering openings 12 adapted to receive a rod 13 slidably therethrough. A

groove 14 is formed in the upper face ofthe walls of the receptacle in spaced relation with the inner edge of the wall, as shown.

There is shown also a cover- 15 for the re Specification of Letters Patent.

' Application filed June 19, 1908. Serial No. 439,348.

ceptacle 10, comprising a flanged member adapted to fit closely over the..receptacle 10 having a downwardly extendin flange portion 16 adapted to engage close y outwardly of the lugs 11 and having a rib 17 spaced inwardly from its edge on the under side, and adapted for registering engagement with the groove 14 in the upper face of the receptacle- 10. An opening 18 is formed in the cover 15 through the central lug at the endof the receptacle, to receive bolts 19 downwardly therethrough, upon the lower end of which is secured a nut 20 the bolt having an eye therethrough at its upper end adapted 'for use to lift the battery.

This invention is adapted to accommodate any desirable number of cells and, as illustrated, two cells are shown divided by a par- I tition 20 extending laterally across and formed integrally with the receptacle 10.

cesses 21 each having a raised portion 2 therearound, as shown. Concentrically of the recesses 21 there are openings 23 fora pur osc to be subsequently indicated. Two of t 1e recesses 21 are formed over each cell, as shown. An opening 24 is formed through the cover 15- over each cell to receive a plug therein, adapted to be removed to allow the escape of gases when a battery is formed therein. 'A cap 25 having a concentric opening 26 therethrough, is engaged over each recess 21 and has a flange 27 extending therearound and adapted to engage over the face of the raised portion 22 adjacent to the recess 21. Disposed concentrically within each recess 21 there is a terminal member 30 comprising yoke members 31 ada ted for engagement with storage battery ates in the usual manner, and having cy lndrical upwardlyextendin portions 32 provided with spaced periphera grooves 33, the upwardly extending portions being en aged slidably through the openings 23 in t e recesses 21,

and stopping short of the raised portion 22,

as shown. A binding post 34 is carried by the ortions 31 and 32 and extends upwardly through the opening 26 and receives thereover a washer 35 and binding nut 36, as shown. Disposed around the portion 32 below the cover 15 there is an insulating washer 37 and in the base of the recess 21 around the portion 32 "there is a similar washer 38, as

shown. V a

In use, the yokes 31 are engaged with Spaced laterally of the cover 15 there are red their respective plates, and adjusted within .in the cells, an the cover 15 p aced downwardly over the receptacle, the-portion 32 being enga ed through the opening 23, as shown. uitable non-conducting vlscid material or liquid is en aged in the groove 14 before putting thelld on, so that a water tight closure is formed around the edge of the receptacle 10 when the cover is introduced thereover. Similar viscid material or liquid isintroduced in the recesses 21 after the cover is'inposition upon the receptacle 10,

land the top 25 then engaged downwardly around the posts 34 and followed by the washer and nuts 35 and 36, as shown. It will be understood that when it is desired to engage wire with the terminal 30 the upper of the nuts 36 isloosened and the wire introduced thereunder upon which the nut 36 may be again tightened, and the wire held firmly.

The cover 15 is provided with spaced lugs 11 around its outer edge and is adapted to engage between the lugs 11 formed upon the' receptacle 10, the lugs 11 having registering o enings 13 therethrough adapted to receive t e rods 13 therethrough in coengagement with the opening 12.

What is claimed is:

1. A storage battery jar adapted to be made of plastic material and comprising a receptacle ortion having spaced outwardly extending ugs around its upper edge, said receptacle havinga groove formed in its upper edge face, a cover having an integral flange therearound, and integral lugs formed inwardly of the flange and adapted to inter mesh wlth thefirst named lugs, said first and second named lugs having registering openings therethrough, said top having a rib formed thereon and adapted to registering engagement in the groove, said groove being adapted to receive a sealin material therein for engpgement with the r1 to hermetically seal t throu h the openings in the first and second name lugs to retain the cover in close engagement with the receptacle against displacement of said rib from sealing engagement in said groove.
